Let's suppose I encrypt a plaintext with one key and a nonce in CTR block cipher mode of operation.
Can I reuse the nonce with another key in another plaintext if I start the block counting with different counters than those used in the first plaintext? I mean (for example), encrypt the first plaintext stopping at the counter 999 and start in the next plaintext with the same key and nonce with counter 1000 and onwards.
